Similar characters of reference designate like'parts throughout thedierent views of the drawings.

The embodiment of the present invention is shown for use in connectionwith a door hingedly supported to swing on a vertical axis at onelongitudinal edge, but it will be obvious that the application of theinvention is not limited to such use, the door being indicated at 14 andthe door frame at 15. The lock casing, designated in a general way by C,is of hollow structure, of rectangular shape and open at the back with aconvexedly formed projection 16 extending from one end as a continuationof one side and extending for substantially one-half the width of thelock casing and opening into the lock casing, as at 17, and having anopening in the underside, as at 18, for a purpose to be hereinafterdescribed. The opening in the back of the casing is closed by a'plate 19secured thereto by engaging a lug 20 projecting from one end of theplate under a shoulder formed in the end wall of the casing adjacenttheprojection 16, as shown at 21, and the other end resting upon a boss22 at the end of the casing opposite to the projection 20 and secured tothe casing by a screw 23 iengaging a recess in said latter end of theclosure plate and threadedinto the boss 22.

- The4 bolt is inthe form of a tongue or pint-le 24 integral with aframe 25 and whereby'it is mounted in the casing to engage in the casingprojection 16 to extend in a plane parallel with the length of the doorand have movement transversely of the lock casing to be projectedfromthe projection opening 18 and drawn thereinto by the movement of itscarrier frame. The bolt carrier frame has a. rectangular portion 26ywhereby it is slidably mounted upon a rod 27 engaging in perforations inthe opposite longitudinal members of said frame, said rod being mountedat its ends, as at 28, in the legs of a U-shaped member 29. The portionof this U-shaped member between the legs is of a length substantiallythe width'ot the casing and is engaged in the casing to lie contiguousto the inner surface of the front wall thereof with the legs ext-endingto and of a length substantially the same as the width of the casing,the terminals `of the legs being undercut, as at 30, to be engaged inopposite recesses 31 in the closure plate whereby said Ushaped member isheld against lateral movement. Oppositely curved portions 32 extend fromthe end of the rectangular portion of the frame 26 opposite to the bolt24, the inner surface of said extended portions 32 being in the arc of acircle whose center is the axis of an actuator for the bolt carryingiframe in the form of an arm 33 fixed on a tubular member 34 rotatablymounted in the front wall of the casing and on a line extendinglongitudinally andV centrally through the casing. The outer ends of saidcurved portions are connected, as at 35. In assembling the bolt in thelock` casing the bolt carrying i frame 25 is `first mounted on the rod23 and the lattersccured in the legsV of the U-shaped member 29. In thiscondition the Vbolt end of the frame is canted downwardly and passedthrough the opening 17 between the projection 16 and lock casing whenthe opposite end is readily engaged over the actuator 33 with theU-shaped member 29 in contiguous relation to the front wall of thecasing. The closure plate is then secured to the casing as hereinbeforedescribed when the bolt frame may be manipulated through the actuator 33to move the boltV to locking position by projecting it from the opening13 of projection 16, or to unlocking position by drawing the bolt intothe .lock projection 16. Vhen the bolt is moved to locking position theactuator 33 through the rotation thereof rides along the upper curvedportion 32 and onto the lower of vsaid portions, and vice versa when thebolt is moved to unlocking position. The bolt is retainedv in unlockingposition by resilient means comprising a strand of resilient wire 36wound intermediate its ends around av pin 37 fixed in the casing withone end engaging affixed abut ment 38 vwhile the opposite end 39slidably engages with the actuator. The lock is scf cured to the door byscrews 40 passing through the lock casing and openings 24 at the endopposite to the bolt engaging projection 36 and threaded into the door`and bv angles to the back 'of the casing, said flange being adapt-ed toengage at the edge of the door with the screws 42 extending into saidedge of the door. The lock is secured on the inner side of the door andthe bolt is adapted to be thrown into and out of locking position by ahand knob 44 fixed yto the end of the carrier 34 for the bolt actuator33 extending through the front wall of the casing. To opera-te the boltactuator from the outer side of the door key operated means is provided.This may be of any conventional form of permutation lock mounted in anopening in the door coaxially with the actuator 33 and including atumbler carrying cylinder 45 and slotted barrel 46 for the engagement ofa key 47, the key barrel being held against rot-ation when the keyv isremoved by tuinblers as is usual. The key barrel is operativelyconnected to the actuator 33 by a bar 48 secured at one end to the keybarrel and the opposite end enga-ging a correspondingly formed openingin a carrier 49 rotatably mounted in the closure plate for a dog 50. Thedog 50 is mounted on the end of the carrier 49 extended through theclosure plate within the casing by engaging nibs 51 extending oppositelyand inwardly from a collarportion of the dog in a transverse slot insaid projecting portion of its carrier and then peening the material ofthe carrier over said collar portion of the dog. An abutment in the'lorm of a lug 52 projecting from the side of ithev actuator arm33opposite tothe dog 50 and eccentric to the axis of the actuator isarranged in the path of movement of the dog and is engaged by the dog asmovement is imparted thereto through its connection with the key barrel46 as the latter is rotated by a key to actuate the bolt carrier frameand move the boltto locking and unlocking position by the key.

As stated, itis an object of the invention to provide a construction oflock wherein the bolt is adapted to be manipulated to move it to lockingand unlocking position by either a hand knob from the inner side ofthedoor, or by key operated means from the outer side of the door, and thekey operated means being adapted to be set to prevent the actuation ofthe bolt actuator by the hand knob when the bolt has been moved tolocking position, or set to permit the actuation of the bolt actuator bythe hand knob when the bolthas been moved to locking position by the keyoperated means. This result is produced by the arrangement oioperatively connecting Vthe key operated means to the bolt actuatorthrough the dog 50 and the abutment 52 on the actuator.

The normal position of the parts with the bolt in unlocking position isas shown in Figures 3 and l0 with the actiuitor 33 eX- tending upwardfrom its carrier and the dog 50 engaging at the right side ol' theactuator abutment 52. In this position the bolt actuator may be actuatedat will to move the bolt to either locking or unlocking position by thehand knob. llVhen the bolt actuator is actuated by the key operatedmeans to actuate it to move the bolt to locking position the dog engageswith the actuator abutment 52 thereby moving the actuator to the left asviewed in Figure l0 to the position shown in Figure 1l. The dog isretained in this position by the tumbler pins co-operating with the keybarrel when the key is withdrawn with the result that the bolt actuatoris held against actuation by the hand knob 44. -When the dog is in theposition shown in Figure 11 a complete revolution will have been givento the dog and the key is in positionto be Withdrawn from the keybarrel. To permit of the actuation of the bolt actuator by the hand knobafter the bolt has been moved to locking position by the key operatedmeans, as just explained, reverse movement is imparted to the dog by thekey from the position shown in Figure ll to that shown in Figures l2 and13 so-that the dog engages at the side of the abutment 52 opposite tothat shown in Figure 11.`

To perform the function o'f latching or locking the door the bolt tongueor pintle 24 (2o-operates with a keeper 53 fixed to the door frame(Figures l2 and 8). This keeper is of rectangular shape in cross sectionto `embracethe corner formed by the edge and one face ot the door frameand secured thereto by screws 54 engaged in openings in both angularportions of the keeper. as shown in Figure 8. A hollow lug 55 projectsfrom one angle portion of the keeper to project from the door frame andhas an opening 56 to the interior thereof. The keeper is of a lengthsubstantially the same as the Width of the lock casing and theprojecting lug 55 is of a length substantially one-halt the keeper andarranged to fit in the angle portion Vformed by the casing projection 16and shaped to conform to said casing projection. .Art-the end of thekeper opposite to the projection lug there is provided a lug 5f? betweenwhich lug and the projection 55 the projecting portion 16 of the casingadapted to engage with thedoor in closed position. This lug 57 preventsany cantine movement oit- Vthe door in an attempt to distort the door inits frame when closed to litt the bolt from the keeper lug 55 and thusopen the door.

By the construction and arrangement of lock "and keeper and themountingr of the same upon the door and door frame it will be obviousthat it will be impossil'ile to remove the lock or the keeper from theinterior of the door'with the object 0f openingthe door since thelock'is securely held to the door by the screws engaging the openings inthe lock flange 43. Also that access cannot be had to the screws 54engaged in openings in that lll() Having thus described my invention, Iy
